DAPRO W-77 Interfacial Tension Modifier acts as an intermediate between areas of high and low surface tension, either within a coating or between the coating and the substrate. It will eliminate or diminish film defects such as crawling, fish eyes, and some forms of cratering. DAPRO W-77 can also promote spreading and uniform film formation on hard-to-wet or contaminated surfaces. DAPRO W-77 also provides excellent recoatability.
